Stephanie, No, it is definitely NOT corona. Corona is an EHV phenomenon, and appears only on transmission lines, not distribution lines such as the lines you described in a residential neighborhood.

Stephanie, Dave is exactly correct. I apologize; I misspoke. We locate the noise first and then determine the source. Then resolve the noise by elimination or mitigation. Hope this helps. Chris AF6PX

Wes, I also have the Sony ICF-SW7600GR. (US model) Keep in mind the built-in ferrite loop antenna is used only up to 1710 kHz. At 1711 kHz and above the radio switches to the telescopic rod antenna.
